This paper presents a genetic algorithm for automating the design process for underground tunnels. The tunnel cross-sectional profile must enclose a prescribed minimum space polygon, and for stability the bending moments in the shotcrete lining must not exceed certain limits. The engineer seeks to achieve these aims while minimizing the volume of rock to be excavated. We describe the five param...

Cleaning and disinfection of public spaces is important it necessary to control the transmission virus. Disinfection prevents a possible other epidemic wave.  In this work, we present sustainable tunnel (SDT). Its role provide maximum protection people passing through in around 10 seconds. The model structure uses renewable energy panel putted at entrance hotels, schools administrations.&n...

The paper presents an experimental verification of conventional PI and PID controller design methods. Nine different synthesis techniques were used to control of airflow speed in laboratory model of hotair tunnel, most of them for both PI and PID version. In the first instance the controlled plant was identified in order to obtain a linear mathematical model and then the controllers were design...

in this article, an algorithm for designing of a supersonic wind tunnel injection nozzle ejector is presented and based on this algorithm, a new ejector is designed for a supersonic wind tunnel. the injection nozzle consists of a volute, a nozzle, and several vanes. designed injection nozzle is simulated numerically, and the results are compared with the present injection nozzle. the results sh...

The potential of machine learning (ML) tools for enhancing geotechnical analysis has been recognized by several researchers. However, obtaining a sufficiently large digital dataset is major technical challenge. This paper investigates the use transfer learning, powerful ML technique, used overcoming size limitations. study examines two scenarios where applied to tunnel support analysis. first s...

Abstract According to the characteristics of tunnel design, BIM entity is created based on digital ground model, forming a set data sources, two-dimensional drawings, three-dimensional models and three expression design forms building information. The system can complete boundaries internal contours, lining cave door auxiliary construction measures design; Among them, intelligent feature softwa...
